Methods and systems for establishing in-flight network traffic policies for personal electronic devices

ABSTRACT

Methods and systems establish a traffic policy for a personal electronic device based on one or more physical characteristics of the device. In some aspects, a database of traffic policies is maintained. The traffic policies are for accessing a network via a wireless communications link. A network access unit receives a request from a personal electronic device to access the network. The request is analyzed to determine a physical characteristic of the device. A traffic policy is established from the database for the device based, at least in part, on the determined physical characteristic of the device. Transmission of network traffic for the device is then scheduled based at least in part, on the established traffic policy.

The present application for patent is a continuation of U.S. applicationSer. No. 16/031,189 by Demange et al., entitled “METHODS AND SYSTEMS FORESTABLISHING IN-FLIGHT NETWORK TRAFFIC POLICIES FOR PERSONAL ELECTRONICDEVICES” filed Jul. 10, 2018, which is a continuation of U.S.application Ser. No. 15/052,828 by Demange et al., entitled “METHODS ANDSYSTEMS FOR ESTABLISHING IN-FLIGHT NETWORK TRAFFIC POLICIES FOR PERSONALELECTRONIC DEVICES” filed Feb. 24, 2016, the entirety of each of whichbeing incorporated herein by reference for any and all purposes.

BACKGROUND

Embodiments relate generally to communications systems.

In-flight entertainment technology is evolving. Some of the first formsof in-flight entertainment included movies shown to an entire cabin ofpassengers via shared video screens. Later, individual screens wereprovided in seat-backs, allowing each individual passenger to choosebetween a finite selection of available movies and/or other programming.Both of these prior solutions relied on media content stored on theaircraft itself, typically either in VHS tape or DVD formats.

More recently, satellite connectivity has been introduced into theaircraft cabin. Connection of in-flight entertainment systems toterrestrial networks via satellite has greatly expanded the role ofin-flight entertainment systems. Not only has satellite connectivityenabled the delivery of live television to the aircraft cabin, but thesesystems have evolved to not only entertain, but also provideconnectivity to information related services such as email and webbrowsing. Moreover, passengers may prefer to seek out their ownentertainment, available via the Internet via streaming servers, insteadof selecting content stored on the aircraft itself.

BRIEF SUMMARY

Disclosed are methods and system to schedule network traffic generatedby devices within an airplane (for example, within a passenger cabin orcockpit of the airplane). Passengers and/or crew members may use avariety of devices to connect to the Internet. For example, businesspeople may prefer to connect via a laptop device, as the laptop mayprovide the power and applications necessary to perform importantbusiness functions, such as communication via email, reviewingelectronic documents, updating spreadsheets, and the like. The casualtraveler may prefer to connect via a tablet computer or cell phone,providing convenient access to their favorite web site or video service.Some passengers may even prefer to use a game device to connect to theinternet, perhaps for a networked game experience with their terrestrialbound peers. Crew members may prefer small devices easily carried, suchas smart phones.

Each of users of these devices may also impose different loads on theaccess network. For example, laptop computers may impart a relativelymodest load on a network, as typical laptop applications such as email,word processing, and spreadsheets do not typically generate high networkusage. In contrast, a smart phone or tablet may indicate a higherpropensity to utilizing streaming services, which may rely on greaterneed by a user for network bandwidth, to provide movies, music, or otherdata intensive content. A game console may perform substantial localprocessing, and thus a user accessing the network via the game consolemay impose a load on the network that is also relatively low. Byunderstanding characteristics of devices used to access an Internetservice, the disclosed methods and systems may provide a user with anetworking experience more tailored to their specific needs. With thedisclosed methods and systems, this tailored experience can be deliveredautomatically, improving ease of use. Furthermore, automatic selectionof traffic policies appropriate for a user device may also avoidinadvertent selection of a traffic policy by a user that is not alignedwith what the user's device can do and how the user will utilize theirnetwork access.

Therefore, the disclosed methods and systems may associate networktraffic policies appropriate for each of the above users based, at leastin part, on one or more characteristics of a device they use to connectto the network. Network traffic for each of these users may then bescheduled based on their associated traffic policies.

The screen size of a device may be one indicator of how the user may usethe device to access the network. For example, larger screen sizes maysupport higher resolution video, which generally requires a largeramount of network data to be transferred to the device. In contrast, asmaller screen size, such as screens on some cell phones, may provide ahigh quality video playback experience using a relatively lowerresolution video, thus, a smaller screen size may indicate that a userwill be viewing lower resolution video on the device, and thus consumingfewer network resources when utilizing this device.

In some aspects, an indicator of screen size associated with a personalelectronic device in communication via the access network may bedirectly or indirectly determined. In some aspects, the screen size maybe determined based on a make and/or model of the device. In someaspects, the make and/or model of the device may be determined based onone or more network messages transmitted by the device to a networkcontroller. For example, in some aspects, indicators of a make and/ormodel number of the device may be included in one or more hypertexttransfer protocol (http) messages, for example, as mime types. Trafficpolicies available to the user may then be determined, at least in part,based on the indicator of the screen size. In some other aspects, one ormore of a transmission control protocol (TCP) signature, media accesscontrol address, dynamic host control protocol (DHCP) signature, orother aspects of a device's network communication may be used todetermine one or more characteristics of the device.

Once one more characteristics of device personal electronic device aredetermined, one or more policies may be identified as potentiallyapplicable for the device based, at least in part, on the one or moredetermined characteristics. In some cases, these policies may differ inone or more of network services (e.g. email, web browsing, filetransfer, virtual private networking, streaming media), and networkcapacity (for example, upload and/or download speed, latency, and/orthroughput) provided by the policies. The policies may also differ inthe amount of time provided for network access under the policy, and/orthe cost incurred by the passenger to utilize each policy.

Furthermore, a route taken by the particular vehicle providing thetransportation may affect network capabilities available during thetransportation activity. For example, some access networks withparticular capabilities may be available via a first route, but onlyaccess networks with fewer capabilities are available via a secondroute. For example, an access network available to a flight over thecontinental United States may provide a higher data throughput than anaccess network available during a flight from San Diego to Hawaii.Therefore, in some aspects, the methods and systems disclosed mayinterface with a flight management computer of the airplane whenselecting one or more traffic policies that may be applied to a deviceof particular characteristics. In some aspects, a route of flight isdetermined from the flight management computer or some other means, fromwhich one or more characteristics of available access network(s) may bedetermined. A traffic policy for one or more passengers may then bedetermined, at least in part, on the characteristics of the availableaccess networks. For example, in some aspects, available capacities ofeach network, in terms of, for example, bandwidth, latency, throughput,packet loss rates, or other measurements of network capacity orcapability, may be utilized to determine a traffic policy for aparticular device or classes of devices.

If multiple policies are available, in some aspects, the user may beprompted to select one policy from the multiple available policies. Insome aspects, this selection may be accomplished via a web-basedinterface between the personal electronic device and a web servermanaged and/or controlled by a access network controller.

One aspect disclosed is a method of providing network access to apersonal electronic device within an airplane via a wirelesscommunications link. The method includes maintaining a database oftraffic policies for accessing a network via the wireless communicationslink, receiving, at a network access unit, a request from the personalelectronic device to access the network, analyzing the request todetermine a physical characteristic of the device, establishing a firsttraffic policy from the database for the personal electronic devicebased, at least in part, on the determined physical characteristic ofthe device; and scheduling transmission of network traffic for thedevice over the wireless communications link according to the firsttraffic policy.

DETAILED DESCRIPTION

In the following description, numerous specific details are set forth toprovide a thorough understanding of the present disclosure. However, onehaving ordinary skill in the art should recognize that the disclosurecan be practiced without these specific details. In some instances,circuits, structures, and techniques have not been shown in detail toavoid obscuring the present disclosure.

FIG. 1 shows a simplified diagram of a communications system 100, whichprovides a context for various embodiments. Many other configurationsare possible having more or fewer components than the communicationssystem 100 of FIG. 1. In the illustrated embodiment, the communicationssystem 100 includes a transport craft 110 in communication with aterrestrial network 160 via a satellite 105, and a gateway 150. Thetransport craft 110 can include a two-way communication system 112 tofacilitate bidirectional communication with the satellite 105. In theillustrated embodiment, the two-way communication system 112 includes anantenna system 170, transceiver 172, modem 174, network access unit 140,wireless access point (WAP) 178, and one or more personal electronicdevices 120 a-n.

The two-way communication system 112 can provide for reception of aforward downlink signal from the satellite 105 and transmission of areturn uplink signal to the satellite 105 to support two-way datacommunications between personal electronic devices 120 within thetransport craft 110 and the terrestrial network 160. The personalelectronics devices 120 can include smartphones, laptops, tablets,netbooks, and the like brought onto the transport craft 110 bypassengers or crew. As further examples, the personal electronic devices120 can include passenger seat back systems or other devices on thetransport craft 110, including passenger and/or crew devices. Thepersonal electronic devices 120 can communicate with the network accessunit 140 via a communication link that can be wired and/or wireless. Thecommunication link can be, for example, part of a local area networksuch as a wireless local area network (WLAN) supported by WAP 178. Oneor more WAPs 178 can be distributed about the transport craft 110, andcan, in conjunction with network access unit 140, provide trafficswitching and routing functionality; for example, as part of a WLANextended service set (ESS), etc.

In operation, the network access unit 140 can provide uplink datareceived from the personal electronic devices 120 to the modem 174 togenerate modulated uplink data (e.g., a transmit intermediate frequency(IF) signal) for delivery to the transceiver 172. The transceiver 172can upconvert and then amplify the modulated uplink data to generate thereturn uplink signal for transmission to the satellite 105 via theantenna system 170. Similarly, the transceiver 172 can receive theforward downlink signal from the satellite 105 via the antenna system170. The transceiver 172 can amplify and downconvert the forwarddownlink signal to generate modulated downlink data (e.g., a receive IFsignal) for demodulation by the modem 174. The demodulated downlink datafrom the modem 174 can be provided to the network access unit 140 forrouting to the personal electronic devices 120. The modem 174 can beintegrated with the network access unit 140, or can be a separatecomponent in some examples.

As described in more detail below, in some implementations, the networkaccess unit 140 may provision and/or schedule network traffic generatedby personal electronic devices 120 a-n. For example, when a user firstattempts to gain access to the network 160, their personal electronicdevice may interface with the network access unit 140 via the wirelessaccess point 178. The network access unit 140 may detect one or morecharacteristics of the personal electronic device, such as whether thedevice is a laptop, cell phone or tablet, and/or the network access unit140 may determine an indicator of the screen size of the device. Thenetwork access unit 140 may then present for display on the device, oneor more options for establishing a traffic policy that controls accessto the network 160 via satellite 105. The options may determine whichnetwork services are available to the device over the access network.For example, the options may determine whether the user has access toone or more of web browsing, email, instant messages, and streamingmedia. Each of the options may also be available for a different cost tothe user. Once the user selects which option they prefer, the user'saccount may be charged an appropriate fee and a traffic policyestablished for the user's device based on the traffic policy selected.The network access unit 140 may then schedule traffic for the user basedon the selected traffic policy.

In the illustrated embodiment, the transport craft 110 is an airplane.Alternatively, the transport craft 110 may be other than an airplane,such as a train, bus, cruise ship, other type of aircraft, etc. Asillustrated, the network 160 can be any type of network and can includefor example, the Internet, an IP network, an intranet, a wide areanetwork (WAN), local area network (LAN), a virtual private network(VPN), a virtual LAN (VLAN), a fiber optic network, a cable network, apublic switched telephone network (PSTN), a public switched data network(PSDN), a public land mobile network, and/or any other type of networksupporting communication as described herein. The network 160 caninclude both wired and wireless connections as well as optical links.

While a single airplane is shown in communication via a singlesatellite, techniques described herein can be applied in many othercommunications environments without departing from the scope of theinventions. For example, one or more transport craft(s) 110 can includeairplanes, trains, buses, cruise ships, etc.; and any or all suchtransport craft(s) 110 can communicate via any one or more suitablecommunications architecture(s) including any suitable communicationslinks or access networks, such as satellite communications systems,air-to-ground communication systems, hybrid satellite and air-to-groundcommunications systems, cellular communications systems, etc. Typically,because of the mobile nature of the transport craft 110, thecommunications architecture will likely involve at least one wirelesscommunications link.

Increasingly, in context of transport craft 110, carriers desire toprovide their passengers with more access to content, which can includeproviding access from sources remote to the transport craft 110 (e.g.,from the Internet and/or other remote sources, as opposed to fromon-craft storage). Carriers may also desire to provide Internet accessto their crew members, to facilitate, for example, ease of communicationwith ground personnel and/or other crew members. This can involvemaintaining one or more communications links between the transport craft110 and a terrestrial network (e.g., via the satellite 105). There istypically a further desire to provide an increasing variety of mediaoptions to passengers and often at a quality (e.g., resolution, colordepth, etc.) that has increased over time. For example, personalelectronic devices with high-fidelity displays are increasinglyubiquitous among passengers. While it may be ideal for the transportcraft 110 to receive all the desired media options at a highest desiredfidelity at all times during transport, this may be cost prohibitive.

FIG. 2 shows another view of the communications system 100 including adetailed block diagram of one example embodiment of the network accessunit 140. Many other configurations of the network access unit 140 arepossible having more or fewer components. While shown as a singlephysical computing device in FIG. 2, in some aspects, one or more of thefunctions discussed below with respect to the network access unit 140may be performed by different physical computing devices. In someaspects, the network access unit 140 may include fewer functionalcomponents than shown in the examiner embodiment of FIG. 2. Moreover,the functionalities described herein can be distributed among thecomponents in a different manner than described herein. In some aspects,the network access unit provides gateway functionality between thepersonal electronic devices 120 on the transport aircraft and the accessnetworks discussed above with respect to FIG. 1. For example, in someaspects, all network traffic transmitted by and/or received by thepersonal electronic devices 120 may be processed by the network accessunit 140. For example, in some aspects, network traffic transmitted tothe personal electronic devices 120 from devices within the network 160may be electronically received by the network access unit 140, whichthen forwards or retransmits the network traffic to the personalelectronic devices 120 according to one or more policies. Similarly, insome aspects, network traffic transmitted to devices on the network 160by the personal electronic devices 120 may be electronically received bythe network access unit 140, which then may forward or retransmit thenetwork traffic to destinations indicated in the network traffic (forexample, to destinations within network 160) based on one or morepolicies.

Consistent with FIG. 1, an in-transport network access unit 140 is incommunication, via satellite 105 (or other suitable communicationsnetwork, as described above) and other components of the two-waycommunication system 112 (not shown in FIG. 2), with a terrestrial basednetwork 160. The network access unit 140 may also be in communicationwith personal electronic devices 120 and, in some aspects, a transportmanagement computer 202. In FIG. 2 and the following discussion, gateway150 and some components (e.g., antenna system 170, transceiver 172,modem 174, WAP 178) of the two-way communication system 112 discussedabove with respect to FIG. 1 are omitted to avoid over complication ofthe drawing.

The illustrated aspect of network access unit 140 includes an electronichardware processor 205, and a network interface 210. The processor 205may be in communication with the network interface 210 via an electronicbus within the network access unit 140 (not shown). The processor maycommunicate with the network interface 210 to transmit and/or receivepackets over a network, such as a network providing connectivity to thewireless access point 178 and/or modem 174 discussed above with respectto FIG. 1. The processor may also communicate over the network interface210 to exchange network messages with an personal electronic device 120and/or a transport management computer 202.

The network access unit 140 also includes an account provisioner 215, aweb server 216, a traffic classifier 217, a rules engine 220, and atraffic scheduler 220. The account provisioner 215, web server 216,traffic classifier 217, rules engine 220, and traffic scheduler 220 maybe portions of a volatile or stable storage, such as a virtual orphysical memory space accessible to processor 205. The accountprovisioner 215, web server 216, traffic classifier 217, rules engine218, and traffic scheduler 220 may include binary data defininginstructions that configure the processor 205 to perform variousfunctions. For example, the account provisioner 215 may includeinstructions that configure the processor 205 to provision access tonetwork 160 by one or more of the personal electronic devices 120 a-n.The web server 216 may store instructions that configure the processor205 to provide functionality associated with delivering electroniccontent via web standards, such as html/http. The traffic classifier 217may include instructions that configure the processor 205 to classifynetwork traffic received by the network access unit 140. For example,the traffic classifier 217 may determine whether traffic is email, webbrowsing traffic, video streaming traffic, messaging traffic, or othertypes of traffic. This information may be used to determine whether thetraffic is allowed by a traffic policy as discussed in more detailbelow. The rules engine 218 may include instructions that configure theprocessor 205 to execute one or more rules that assign a traffic policyto a personal electronic device 120 based on one or more characteristicsof the network device. The traffic scheduler 220 may includeinstructions that configure the processor 205 to schedule networktraffic generated by the personal electronic devices 120 a-n.Instructions in one or more of the account provisioner 215 and/ortraffic schedule 220 may configure the processor 205 to read data fromthe policy database 225. For example, in some aspects, the processor 205may read data from the policy database 225 in order to determine atraffic policy to apply to network traffic generated by one or more ofthe personal electronic devices 120 a-n. The policy database 225 andrules database 228 are discussed in detail in FIG. 3 below. While FIG. 2shows the network access unit 140 as one physical device, one of skillin the art would understand that in some aspects, the functionsdiscussed above and below relating to the network access unit 140 may insome implementations be implemented on multiple physical devices. Forexample, in some aspects, functionality associated with each of theaccount provisioner 215, web server 216, traffic classifier 217, rulesengine 218, and traffic scheduler 220 may each be provided on a separatephysical device having its own dedicated electronic hardware processor,memory, and network interface. Additionally, in some implementations,the policy database 225 and rules database 228 may also be implementedon separate devices from one or more of the account provisioner 215, webserver 216, traffic classifier 217, rules engine 218, and trafficscheduler 220. How the functionality discussed above and below ispartitioned across one or multiple physical hardware devices does notsubstantially affect the methods and systems disclosed herein. WhileFIG. 2 shows the policy database 225 and rules database 228 included aspart of the network access unit 140, in some other implementations,these components may be accessible via the network 160. In some of theseaspects, the network access unit may be configured to cache at least aportion of the policy data 225 and/or rules database 228 in a localmemory to provide for reliable and performant access to data containedtherein.

FIG. 3 shows exemplary relational database table structures for atraffic policy table 260, device table 270, and rules table 280. In someaspects, the traffic policy table 260 is included as part of the policydatabase 225 discussed above with respect to FIG. 2. In some aspects,the rules table 280 may be included as part of the rules database 228discussed above with respect to FIG. 2.

The traffic policy table 260 stores data defining one or more trafficpolicies 261 a-n. Each traffic policy includes a policy identifier 262,and one or more network control parameters 264 a-n. Each of networkcontrol parameters 264 a-n may define how network traffic managed by therespective policy is controlled. For example, a first network controlparameter 264 may indicate one or more network services available underthe respective policy. For example, the first network control parametermay indicate whether one or more of web browsing, instant messaging,email, audio streaming, video streaming, and virtual private networkaccess is provided under the policy. In some aspects, a second networkcontrol parameter defined by a policy 261 may define one or more networkscheduling parameters for network traffic controlled under the policy.For example, in some aspects, the second network control parameter maydefine a committed information rate (CIR) and/or a peak information rate(PIR) for network data controlled under the policy.

The device table 270 may define which traffic policy in traffic policytable 260 is applied to network traffic generated by a particularpersonal electronic device 120. The device table 270 may include arecord 271 a-n for each personal electronic device 120 managed by thenetwork access unit 140. Each device entry 271 may include a deviceidentifier 272 uniquely identifying a particular personal electronicdevice 120. For example, in some aspects, the device identifier 272 maybe one or more of a station address of the device, a hash of one or moreproperties of the device, and a globally unique identifier of thedevice. Each device entry 271 also includes one or more determinedcharacteristics 274 a-n of the device. Each device entry 271 may alsoinclude an indicator of which traffic policy in the traffic policy table260 should be used to manage network traffic generated by the personalelectronic device 120. For example, if the personal electronic device120 corresponding to device entry 271 a has a policy identifier field276 equivalent to the policy identifier field 262 of policy 261 a, thennetwork traffic generated by the personal electronic device 120 ismanaged by policy 261 a.

In this exemplary embodiment, the rules table 280 stores one or morerules 281 a-n used to establish a traffic policy for a particularpersonal electronic device 120. In some aspects, the rules 281 a-n maybe evaluated in a particular order. For example, in some aspects therules may be evaluated from the “top” of the rules table 280 (lowerorder rows) toward the bottom (higher order rows) of the rule table 280.In some aspects, the rules may be executed in a sequence defined by therule ids 282. The rules 281 a-n also include one or criteria. In someaspects, if all of the criteria specified in a particular rule aresatisfied, then the rule becomes active and any actions specified by therule are taken. Otherwise, in some aspects, rules below the current ruleare evaluated.

Each rule 281 includes a rule identifier 282, and one or more criteria284 a-n relating to one or more corresponding characteristics of anpersonal electronic device 120, and/or characteristics of availableaccess networks. For example, the criteria 284 a-n may be applied tocorresponding characteristics 274 a-n of an personal device, stored inthe device table 270. In some implementations if the criteria 284 a-nspecified in a rule 281 match characteristics 274 a-n of a personalelectronic device 120, the particular policy corresponding to policyidentifier 288 in the rule 281 may be stored in the policy identifierfield 276 of the device table 270. This may establish the particularpolicy as applicable to the particular device identified in the deviceidentifier field 272 of the device table 270.

A rule 281 may also include one or more criteria 286 a-n relating to thetransportation activity. For example, one transport activity criteriamay evaluate a route taken during the transport activity (such as aroute of an airline flight), or may evaluate a length of time remainingin the transportation activity. In these example, a criteria may specifythat if the length of time remaining in the transportation activity ismore than a threshold period of time (or less than a threshold period oftime), the criteria is satisfied. Similarly, a criteria 286 may specifythat if a route of flight is within particular geographic coordinates,then the criteria are satisfied (or not satisfied).

In particular, some routes of flight may include coverage by an accessnetwork (such as a satellite network) having a first set ofcharacteristics, such as capacity, bandwidth, latency, and the like. Asecond route of flight may have coverage by a second access networkhaving a second set of characteristics. Variations in thesecharacteristics may effect which policy should be established for aparticular personal electronic device 120. As another example, a timeremaining in a transport activity, such as an airplane flight, mayeffect which policy should be established for a particular personalelectronic device 120. Xport criteria 286 a-n may be utilized toimplement these types of features in some embodiments.

As a more specific example of how rules may establish a policy for adevice, in one implementation a hypothetical rule 281 a may be definedby rule table 280 to identify policy 261 a in its policy identifierfield 288. The rule 281 a may also include a first criteria 284 aevaluating whether a device is a laptop computer. If the device is alaptop computer, then the criteria 284 a is satisfied. In thisparticular implementation, the rule 281 may include only this onecriteria 284 a. In this implementation, policy 261 would be establishedfor all personal electronic devices 120 a-n that are determined to belaptop computers. In this hypothetical example, the rules table 280 mayinclude a second rule 281 b. Rule 281 b may identify policy 261 b (notshown in FIG. 3) in its policy identifier field 288. Rule 281 b mayinclude no criteria. In this hypothetical example, if the rules 281 areevaluated “top down” as described above, rule 281 b may function as adefault rule, and establish policy 261 b for all personal electronicdevices that are not determined to be laptop computers via device table270.

In some implementations, a plurality of policy identifiers 288 a-n maybe associated with a particular rule 281. In these implementations, whencriteria 284 and/or 286 of a particular rule 281 are a match with aparticular personal electronic 120, one of the plurality of policyidentifiers 288 a-n may be selected to establish a policy for thepersonal electronic device 120. In some aspects, this selection may beperformed automatically, based on one or more criteria. In some otheraspects, this selection may be provided by input received from thepersonal electronic device. Once the selection is made, the selectedpolicy may be established as the policy for or applied to networktraffic generated by the personal electronic device 120.

FIG. 4 is a message sequence diagram showing communication between apersonal electronic device 120 and the network access unit 140 during aprovisioning process, such as provisioning process 600 discussed belowwith respect to FIG. 6. FIG. 4 shows that a personal electronic device120 may transmit a connection request 404 directly or indirectly, to thenetwork access unit 140. For example, the personal electronic device 120may send a connection request to a destination node having a particularIP address. In some aspects, the connection request 304 may be atransmission control protocol (TCP) synchronization (syn) messageindicating the particular IP address as a destination IP address in anIP header of the connection request. In some other aspects, theconnection request transmitted in block 404 may be an http “Get”message, transmitted over a previously established tcp connection.

In block 408, the network access unit 140 receives the connectionrequest from the personal electronic device 120. In some aspects, theremay be a further message exchange 409 a-b between the personalelectronic device 120 and the network access unit 140. One or morenetwork data messages may be included in the further message exchange409 a-b between the personal electronic device 120 and the networkaccess unit 140. For example, in some aspects, the network access unit140 may transmit an http redirect message to the personal electronicdevice 120 in response to the http get request described above. The httpredirect message may cause the personal electronic device 120 to performan additional http get request to the web server 216 controlled by thenetwork access unit 140. One or more messages associated with thesefeatures may be exchanged as part of further message exchange 409 a-b.

In block 412, the network access unit 140 determines one or morecharacteristics of the device. The determination may be based on one ormore of the connection requests received in block 408 and/or additionalmessages received from the personal electronic device 120 as part offurther message exchange 409 a-409 b. From one or more of these networkmessages, the network access unit may determine network client data suchas one or more of a media access control address, dynamic hostconfiguration protocol (DHCP) fingerprint of the network access unit140, one or more http headers, a user agent (UA) string from an httpheader transmitted by the personal electronic device 120, and atransmission control fingerprint of the personal electronic device 120.The determination of device characteristics may then be based on thenetwork client data.

As discussed above with respect to characteristics 274 a-n of the devicetable 270, these determined network characteristics may relate to a formfactor of the device, such as whether the device is a laptop, cellphone, game device, or tablet, and/or an indication of a screen sizeand/or resolution of the device. In some implementations, block 412 mayinclude storing the determined characteristics of the device to thedevice table 270 or a similar data structure. In particular, block 412may store values in one or more of device characteristic database fields274 a-n.

In block 416, one or more policies are identified in the policy databasebased on the one or more determined characteristics of the personalelectronic device 120. As discussed above with respect to the rulesengine 218 and rules table 280, in some implementations, identificationof the one or more policies in block 416 may be based on an evaluationof one or more rules, with each rule comparing at least one or morecharacteristics of the device to one or more corresponding criteria. Ifcriteria defined by a rule match a device's characteristics, one or morepolicies identified by the rule may be available for selection. In someother implementations, a rules engine and rules database may not beutilized. Instead, conditional logic within the account provisioner 215may identify one or more policies in the policy database 225 based onthe one or more determined characteristics of the device.

In some aspects, the policies may be further identified based on routeinformation received from a database. For example, origin anddestination locations, or city pairs, coordinates, airport identifiers,or the like may be used to determine a policy. This information may beconsidered by the rules engine 218 when determining which trafficpolicies are application to the personal electronic device 120. In someaspects, the policies may further be identified based on data receivedfrom the transport management computer 202, discussed above with respectto FIG. 2. For example, information relating to a duration of thetransport activity, such as an airline flight, may be received from thetransport management computer by the network access unit 140, andconsidered by the rules engine 218 when determining which trafficpolicies are applicable to the personal electronic device 120. In someaspects, one or more of an origination point and/or destination pointfor the transport activity may be received from the transport managementcomputer 202. Alternatively, one or more waypoints or informationdefines a route of the transport activity (such as an airline flight)may be received from the transport management computer 202, or aseparate database and utilized to determine an applicable trafficpolicy.

In block 420, the identified policies are presented for display to thepersonal electronic device 120. In some aspects, presenting theidentified policies for display includes transmitting one or morenetwork messages to the device indicating the identified policies. Forexample, in some aspects, a user interface may be presented on thepersonal electronic device 120 via a network message exchange betweenthe network access unit (and specifically web server 216 in someaspects) and the personal electronic device 120. In some aspects, thisnetwork message exchange may be an http message exchange, for example,if the user interface is implemented using hypertext markup language(html). Alternatively, the network message exchange may includeproprietary messages, for example, if the user interface is presented onthe display of the client 120 via a proprietary or industry standardplug-in technology.

The personal electronic device 120 may then display the optionspresented by the network access unit 140.

FIG. 5A shows an example presentation 500 of traffic policy optionsdisplayed on a personal electronic device 120, with the personalelectronic device 120 having a determined characteristic of asmartphone. As shown, two options 510 a-b are presented on the display.The first option 510 a provides access to web browsing, messaging, andemail applications on a device having a determined characteristic of asmartphone, and may be selected by selecting the control 515 a. Thesecond option 510 b also provides video streaming, for an additionalcost relative to option 510 a, and may be selected by selecting control515 b. While two options are shown in FIG. 5A, the disclosed methods andsystems could provide more or fewer options. For example, at least one,two, three, four, five, six, seven, eight, nine, or ten options arecontemplated.

In some implementations, the smaller screen size associated with thesmartphone computer is associated with a smaller load imparted on thenetwork by a user utilizing these types of devices. For example, since asmartphone typically has a smaller screen size than other personalelectronic devices, such as laptops, a lower resolution of video datamay be provided while maintaining a satisfactory viewing experience forthe user of a smartphone, when compared to a resolution that may benecessary to provide an equally satisfying experience for a laptop ortablet user.

Once the determined traffic policy options are displayed on the personalelectronic device 120, a user of the personal electronic device 120 mayselect one of the buttons 515 a-b to select one of the options 510 a-b.

FIG. 5B shows another embodiment of a user interface 550 of trafficpolicy options displayed on a personal electronic device 120 having adetermined characteristic of a laptop. As shown, three options 555 a-care presented on the display. The first option 555 a provides access toweb browsing, messaging, and email applications on a laptop, and may beselected via control 560 a. The second option 555 b also provides videostreaming, for an additional cost relative to option 555 a, and may beselected via control 560 b. The third option 555 c also provides thesame features as option 555 b and also includes high definition videostreaming. Option 555 c may be selected via control 560 c. While threeoptions are shown in FIG. 5B, the disclosed methods and systems couldprovide more or fewer options. For example, at least one, two, three,four, five, six, seven, eight, nine, or ten options are contemplated.

In some implementations, the larger screen size associated with thelaptop computer is associated with a larger load imparted on the networkby a user utilizing these types of devices. For example, since a laptoptypically has a larger screen size than other personal electronicdevices, such as smartphones, a higher resolution of video data may needto be provided in order to maintain a satisfactory viewing experiencefor the user of a laptop, when compared to a resolution that may benecessary to provide an equally satisfying experience for smartphoneuser. Note the cost of the premium plan in FIG. 5A and the premium planin FIG. 5B are different. This difference may be based on the type ofdevice in some aspects. For example, the smartphone user of FIG. 5A maybe offered a network service plan with similar characteristics as anetwork service plan offered to a laptop user in FIG. 5B, but the pricefor these plans may be different because they are offered to users withdifferent types of devices, a smartphone if FIG. 5A and a laptop user inFIG. 5B.

Returning to the discussion of FIG. 4, the personal electronic device120 may then receive the selection from the user as described in block430. Data indicating the selection may then be transmitted from thepersonal electronic device 120 to the network access unit 140. In block435, the network access unit establishes the selected traffic policy foruse with the personal electronic device 120. As described above withrespect to FIG. 3, in some aspects, establishing a selected trafficpolicy for use with the personal electronic device 120 may includestoring an indicator of the selected policy in a row of the device table270. Specifically, a row identifying the particular personal electronicdevice 120 via device identifier field 272 may be updated to indicatethe selected policy. For example, the policy identifier field 276 may beupdated.

FIG. 6 is a method of providing network connectivity to an personalelectronic device 120. In some aspects, process 600 may be performed bythe network access unit 140, as illustrated in FIG. 2. For example, insome aspects, the electronic hardware processor 205 may be configured byinstructions in one or more of the account provisioner 215 and/ortraffic scheduler 220 to perform the functions described below withrespect to process 600.

As discussed above, process 600 may enable traffic policies to beapplied to personal electronic devices 120 a-n based on one or morecharacteristics of the device. Characteristics of the device, such as adevice's screen size, may be indicators of a maximum resolution of videodata that continues to provide incremental value to that device. Forexample, since some cell phones may generally include smaller screensthan, for example, laptop computers, lower resolution video data may beprovided to cell phones as compared to laptop computers, while stillmeeting expectations of both the cell phone and laptop user. By applyingappropriate traffic policies to the laptop and cell phone devices, theresolution of video provided to those devices may be effectivelycontrolled. For example, many streaming media protocols includecapabilities that enable sensing of a network capacity. These protocolsmay then adapt the resolution of video provided over the stream based onthe sensed capacity. In some aspects, the traffic policies applied tothe different types of devices may affect the capacity sensed by thesestreaming protocols, thereby altering the resolution of video provided.

In block 608, a database of traffic policies is maintained. Maintaininga database of traffic policies may include storing data defining thetraffic policies, for example, via a stable storage medium.

The stored traffic policies may relate to accessing a network via awireless communications link. In some aspects, the network may be thenetwork 160 discussed above, while the wireless communication link mayinclude the wireless link between the transport craft 110 and satellite105.

A traffic policy may define network services available to a device underthe policy. For example, the policy may define whether one or more ofweb browsing, email, instant messaging, streaming media, and virtualprivate networking is available to a device under the policy.

The traffic policies may define one or more scheduling parameters fornetwork traffic associated with the policy. In some aspects, the policymay define one or more transmission weights and/or priorities for datatransmitted by a device operating under the policy. For example, thepolicy may indicate a priority for transmission relative to otherpersonal electronic devices 120 a-n. In some aspects, the policy maydefine a committed information rate (CIR) and a peak information rate(PIR) for data transmitted under the policy.

In some aspects, the policy may define a cost or fee charged to a userof a device operating under the policy. In some aspects, the policy maydefine an elapsed time period during which network access is enabled fora device under the policy. After a personal electronic device 120 hasbeen provided network access for the defined elapsed time period, nofurther network access may be allowed under the policy in some aspects.In some aspects, the database maintained in block 608 may include atleast the database structure described above with respect to FIG. 3, andtraffic policy table 260, and/or device table 270.

In block 612, a request to access the network is received from anpersonal electronic device. The request may be in the form of a networkmessage transmitted by the personal electronic device to the networkaccess unit 140 in some aspects. As discussed above, when attempting toconnect to a network, a personal electronic device 120 may perform adomain name service to establish a destination Internet protocol (IP)address based on a host name (such as “viasat.com”).

After a destination IP address is obtained by the personal electronicdevice 120, a connection request to the IP address may be initiated bythe device, in the form of a transmission control synchronization (orSYN) packet. In some aspects, block 612 may include the exchange of aplurality of network messages or packets between the personal electronicdevice and, for example, the network access unit 140. For example, insome aspects, the personal electronic device may establish a TCPconnection with the network access unit. The personal electronic devicemay then request, for example, content via the established TCPconnection. In some aspects, block 612 may include one or more of thefunctions discussed above with respect to blocks 408, 409 b in FIG. 4.

In block 616, the request for network access is analyzed to determine aphysical characteristic of the personal electronic device. In someaspects, a plurality of packets including the request may be analyzed todetermine a physical characteristic of the device. For example, asdiscussed above with respect to blocks 404, 408, 409 a-b, the one ormore messages analyzed in block 616 may include a TCP SYN packet and/orhttp get request. In some aspects, one or more third party libraries maybe utilized to determine one or more physical characteristics of thepersonal electronic device. For example, one typical library is providedby Netbiscuits™ of the United Kingdom. The analysis may includeconsideration of one or more of TCP signatures, http mime types, and/orother characteristics of network packets generated by the personalelectronic device 120.

The physical characteristics determined in block 616 may include one ormore of a form factor of the device (e.g. laptop, cell phone, portablegame device, tablet), an indicator of screen size of the device, anindicator of a manufacturer and/or model of the device, an indicator ofa processing capability of the device, and an indicator of the size ofvolatile memory of the device.

In block 620, a traffic policy from the database is established for orassigned to the personal electronic device, based at least in part, onthe determined physical characteristic(s). In some aspects, the trafficpolicy may be established using a rules engine and rules table similarto that described above with respect to FIG. 3. In some implementations,the one or more characteristics of the device may be compared to one ormore respective criteria defined by one or more rules. In some simpleexample, three separate rules may be defined, one for each of a devicecharacteristic indicating a laptop computer, tablet computer, and cellphone.

In response to a set of rule criteria matching characteristics of thepersonal electronic device, a traffic policy defined by the rule may beassociated with or assigned to the personal electronic device 120. Insome aspects, as shown in FIG. 3, if no criteria match the knowncharacteristics of the personal electronic device, a default policy maybe assigned, as provided for by example rule 281 n.

In some aspects, block 620 may determine a plurality of trafficpolicies, including the first traffic policy, from the database based onthe determined physical characteristic(s) of the device. Data indicatingthe plurality of traffic policies may then be provided to the personalelectronic device 120 for display. For example, as discussed above withrespect to FIG. 3, a rules table may include a rule, such as rule 281 a,that identifies multiple policies 288 a-n that may apply when the rule'scriteria 284 a-n are met. In this example, the plurality of policies maybe each of the policies identified by records 288 a-n.

In some aspects, the plurality of traffic policies may be establishedbased on a route of flight of an aircraft. For example, as discussedabove, in some aspects, route information may be obtained from a flightinformation database or a flight management computer. Information suchas source and/or destinations of the flight, geographic coordinates,airport codes, etc may allow determination of which particular accessnetworks are available during the flight, and one or more capabilitiesof the available access networks. The selection of traffic policies maybe made so as to be compatible with the available access networks. Forexample, if the aircraft is passing through a region having accessnetworks of relatively lower capabilities, the available transmissionpolicies may reflect that. For example, in some aspects, certain networkservices may not be available when access is available via particularaccess networks with reduced capabilities. Alternatively, prices forparticular services may be adjusted based on the access networksavailable over a route of flight. In some aspects, access networks ofrelatively higher capabilities may be available over a particular routeof flight. In these aspects, establishment of the traffic policy andselection of the plurality of traffic polices may be based on the highercapabilities. For example, greater capabilities may be offered in someaspects. For example, high definition movies may be provided whencertain access networks are available but not when other access networksare available.

Block 620 may also include providing, to the personal electronic device120, data indicating the plurality of traffic policies for display. Forexample, as discussed above with respect to block 420 of FIG. 4,presenting or providing for display may include transmitting one or morenetwork messages to the personal electronic device 120 indicating thedetermined traffic policies. In some aspects, these network messages maycause a user interface to be displayed on the personal electronic device120, enabling a user of the device to make a selection among thepresented plurality of traffic policies. Input may then be received fromthe device indicating which of the plurality of traffic policies wasselected. The first traffic policy may then be established for thepersonal electronic device based on the selection.

In block 626, transmission of network traffic for the device isscheduled over the communications link according to the establishedtraffic policy. In some aspects, block 625 may be performed by theprocessor 205 configured by instructions stored in the traffic scheduler220.

In some aspects, block 626 also includes providing network services tothe device based on the established traffic policy. For example, asdiscussed above, a traffic policy 261 may include one or more parameters264 defining which network services are allowed and/or prohibited underthe policy. In some aspects, block 626 may include performing trafficclassification of network traffic received from a personal electronicdevice, to determine, for example, whether the traffic is web browsing,email, messaging, video streaming, or another form of network traffic.In some aspects, traffic classification may be performed by instructionsstored in the traffic classifier 217, discussed above with respect toFIG. 2. Based on the classification, block 626 may allow networkservices defined as allowed under the established policy and prohibit orreject services defined as prohibited under the policy. Allowing networkservices may include forwarding and/or relaying network messagesassociated with an allowed network service across a gateway, router, orfirewall, such as network access unit 140. Prohibiting a network servicemay include dropping or not forwarding network messages associated witha prohibited network service. In some aspects, prohibiting a networkservice may include actively blocking or “naking” network messagesassociated with the prohibited network service. In some aspects, asdiscussed above, a traffic policy may indicate that one or more ofemail, web browsing, instant messaging, chat, streaming media, virtualprivate networking, or file transfers are either prohibited or allowedunder the policy.

FIG. 7 is one example of scheduling transmission of network traffic overa communications link according to an established traffic policy. Insome aspects, process 700 may be performed by the processor 205,configured by instructions included in the traffic scheduler 220 d. Insome aspects, process 700 may be performed as part of block 626,discussed above.

In block 705, personal electronic device 120 with data queued fortransmission are determined. For example, in some aspects, scheduling ofdata for transmission may occur in repetitive cycles, with process 700demonstrating one example cycle of allocation. During each cycle, one ormore personal electronic devices 120 a-n of a network may have dataavailable for transmission. For these personal electronic devices 120a-n may have transmitted network data to the network access unit 140,where the network access unit is functioning as a router, bridge, orgateway between the personal electronic devices 120 a-n and the network160. In some aspects, block 705 determines which devices have databuffered or waiting for transmission during a particular cycle. This mayinclude scanning one or more data queues to identify which users havedata waiting.

In block 710, a committed information rate (CIR) and peak informationrate (PIR) are determined for each of the devices determined in block705. In some aspects, the CIR and PIR may be obtained from trafficpolicies assigned to or controlling transmission of each of thedetermined devices. For example, as discussed above with respect to FIG.3, a particular transmission policy 261 may include one or moretransmission parameters 264 a-n. In some aspects, one or more of thetransmission parameters 264 a-n may define a CIR and PIR for therespective transmission policy. In these aspects, block 710 may thenread the CIR and PIR stored in the policy record 261 to determine theCIR and PIR.

In block 715, data is allocated for transmission according to the CIRfor each device with data queued for transmission. For example, the CIRparameter may indicate a minimum amount of each device's data is to betransmitted during each allocation cycle discussed above. By allocatingdata according to the CIR in block 715, the minimum amount of data foreach device is fulfilled according to the CIR.

In block 720, a remaining network capacity is determined based on theCIR allocation. For example, allocation of each device's CIR in aparticular allocation cycle according to block 715 will consume aportion of available network capacity. In some aspects of b lock 720,the remaining capacity may be determined according to: remainingcapacity=available capacity−CIR allocation for each device.

In block 725, the remaining capacity is proportionally allocatedaccording to the determined PIR scheduling parameters. For example, thePIR parameters of each device with data queued for transmission maydefine a proportional allocation of the remaining network capacity for aparticular allocation cycle that should be allocated to each device.

In block 730, data is transmitted according to the allocations in block715 and 725. For example, in some aspects, instructions in thetransmission scheduling module 220 may transmit data according to theallocations determined in blocks 715 and 725 via the processor 205 andnetwork interface 210, to the modem 174, shown in FIG. 1. The data maythen be transmitted to the state little 105 and then to the network 160,also shown in FIG. 1.

As discussed above, process 700 may be repeated for each allocationcycle of the transmission scheduler 220. In some aspects, thetransmission scheduler 220 may utilize a different process forscheduling transmissions of the personal electronic devices 120 a-naccording to the assigned transmission policies. The above descriptionof process 700 is just one example implementation.

FIG. 8 is a flowchart of a method for modifying an established trafficpolicy for a user. In particular a user may wish to communicate with thenetwork 160 via more than one device during a transportation activitysuch as an airline flight. In this situation, the user may firstestablish a communication session using a first device and a firstestablished traffic policy. The user may then attempt to connect to thenetwork 160 via a second device. The first traffic policy may or may notbe appropriate for the second device. Thus, process 800 modifies thetraffic policy as necessary such that the user may have a policyappropriate for all devices with which a connection to network 160 isdesired. The description below assumes that process 600 has already beenperformed and therefore, a first traffic policy has been established forthe first device.

In some aspects, process 800 may be performed by the network access unit140. In some aspects, instructions stored in one or more of the accountprovisioner 215, rules engine 218, traffic scheduler 220, and/or webserver 216 may configure the processor 205 to perform one or more of thefunctions discussed below with respect to process 800.

In block 805, first subscriber identification information is receivedfrom a first personal electronic device 120. The subscriberidentification information may include a user name and password in someaspects. In some aspects, the subscriber identification information mayinclude biometric information of the subscriber. Alternatively, thesubscriber identification information may include a station address of adevice associated with the subscriber.

In block 810, a request is received from the subscriber to access thenetwork using a second personal electronic device 120. For example, insome aspects, to establish the traffic policy for the first personalelectronic device 120, a subscriber identification may also beassociated with the traffic policy and/or the first personal electronicdevice 120. For example, a user account may be established to providefor establishment of the traffic policy for the first personalelectronic device 120.

The user may then utilize a second personal electronic device 120 toattempt to connect to the network 160. In some aspects, in response tothe attempt by the second personal electronic device 120 to access thenetwork 160, a user interface may be presented for display on the secondpersonal electronic device 120. For example, as shown in FIG. 5A, theuser interface 500 may be presented in some aspects, giving a user anoption of various service plans from which to choose.

In block 820, the request from the second device is analyzed todetermine a physical characteristic of the second device. In someaspects, block 815 may include one or more of the functions discussedabove with respect to block 616, but applied to the second personalelectronic device 120 instead of the first personal electronic device120.

In block 825, second subscriber information is received from the seconddevice. For example, as shown in FIG. 5A, a subscriber may login viacontrol 525 when presented with a user interface. The second subscriberinformation received in block 825 may, in various embodiments, conformto one or more of the types of subscriber information described abovewith respect to block 805.

In block 830, a second plurality of traffic policies are determinedbased on the second physical characteristic and in response to thesecond subscriber identification information received from the seconddevice. For example, in some aspects, the second plurality of trafficpolicies may be determined based on the prior selection of the firsttraffic policy in process 600, discussed above with respect to FIG. 6.For example, if the user selected a plan that included support formultiple devices as the first traffic policy, then the second pluralityof traffic policies may include the first traffic policy, as the firsttraffic policy may be adequate to support network access by either thefirst or second device. Alternatively, if the first traffic policy doesnot accommodate multiple devices, the second plurality of trafficpolicies may include policies supporting multiple devices, but may notinclude the first traffic policy.

In block 835, data indicating the plurality of traffic polices areprovided for display on an electronic display of the second device. Asdiscussed above with respect to block 620, in some aspects, providingdata for display may include transmitting data over a network to thesecond device, the data indicating a user interface to display on anelectronic display of the second personal electronic device 120. In someaspects, the data may define an interface similar to that shown in FIG.5A and discussed above on an electronic display of the second electronicdevice.

In block 840, input is received from the second device defining aselection of a second traffic policy of the plurality of trafficpolicies. In some aspects, the input may be received over a network fromthe second device, in response to a user selecting a control on a userinterface corresponding to the selected traffic policy.

In some aspects, a comparison of the first traffic policy (selected whenprocess 600 was performed) is compared to the second policy selected inblock 840. The comparison may determine a first set of one or morecapabilities present in the first traffic policy that are not present inthe second traffic policy. Similarly a second set of capabilities may bedetermined that are present in the second traffic policy but not presentin the first traffic policy. In some aspects, an indication of one ormore of the first and second set of capabilities may be presented to thesecond device for display. For example, in some aspects, if the secondtraffic policy provides fewer capabilities than the first traffic policyin at least one respect, data indicating a warning message to the usermay be provided to the second device for display. In some aspects,differences between the first and second traffic policies may also beindicated in the message.

In block 845, network traffic from the second device is scheduled basedon the selected traffic policy. In some aspects, one or more of thefunctions discussed above with respect to block 616 of FIG. 6 may beincluded in block 845. In some aspects, block 845 may be implemented byinstructions included in the traffic scheduler 220 of FIG. 2, inconjunction with the processor 205.

In describing the present invention, the following terminology will beused: The singular forms “a,” “an,” and “the” include plural referentsunless the context clearly dictates otherwise. Thus, for example,reference to an item includes reference to one or more items. The term“ones” refers to one, two, or more, and generally applies to theselection of some or all of a quantity. The term “plurality” refers totwo or more of an item. The term “about” means quantities, dimensions,sizes, formulations, parameters, shapes and other characteristics neednot be exact, but can be approximated and/or larger or smaller, asdesired, reflecting acceptable tolerances, conversion factors, roundingoff, measurement error and the like and other factors known to those ofskill in the art. The term “substantially” means that the recitedcharacteristic, parameter, or value need not be achieved exactly, butthat deviations or variations including, for example, tolerances,measurement error, measurement accuracy limitations and other factorsknown to those of skill in the art, can occur in amounts that do notpreclude the effect the characteristic was intended to provide.Numerical data can be expressed or presented herein in a range format.It is to be understood that such a range format is used merely forconvenience and brevity and thus should be interpreted flexibly toinclude not only the numerical values explicitly recited as the limitsof the range, but also interpreted to include all of the individualnumerical values or sub-ranges encompassed within that range as if eachnumerical value and sub-range is explicitly recited. As an illustration,a numerical range of “about 1 to 5” should be interpreted to include notonly the explicitly recited values of about 1 to about 5, but alsoinclude individual values and sub-ranges within the indicated range.Thus, included in this numerical range are individual values such as 2,3 and 4 and sub-ranges such as 1-3, 2-4 and 3-5, etc. This sameprinciple applies to ranges reciting only one numerical value (e.g.,“greater than about 1”) and should apply regardless of the breadth ofthe range or the characteristics being described. A plurality of itemscan be presented in a common list for convenience. However, these listsshould be construed as though each member of the list is individuallyidentified as a separate and unique member. Thus, no individual memberof such list should be construed as a de facto equivalent of any othermember of the same list solely based on their presentation in a commongroup without indications to the contrary. Furthermore, where the terms“and” and “or” are used in conjunction with a list of items, they are tobe interpreted broadly, in that any one or more of the listed items canbe used alone or in combination with other listed items. The term“alternatively” refers to selection of one of two or more alternatives,and is not intended to limit the selection to only those listedalternatives or to only one of the listed alternatives at a time, unlessthe context clearly indicates otherwise. The term “coupled” as usedherein does not require that the components be directly connected toeach other. Instead, the term is intended to also include configurationswith indirect connections where one or more other components can beincluded between coupled components. For example, such other componentscan include amplifiers, attenuators, isolators, directional couplers,redundancy switches, and the like. Also, as used herein, including inthe claims, “or” as used in a list of items prefaced by “at least oneof” indicates a disjunctive list such that, for example, a list of “atleast one of A, B, or C” means A or B or C or AB or AC or BC or ABC(i.e., A and B and C). Further, the term “exemplary” does not mean thatthe described example is preferred or better than other examples. Asused herein, a “set” of elements is intended to mean “one or more” ofthose elements, except where the set is explicitly required to have morethan one or explicitly permitted to be a null set.

Various changes, substitutions, and alterations to the techniquesdescribed herein can be made without departing from the technology ofthe teachings as defined by the appended claims. Moreover, the scope ofthe disclosure and claims is not limited to the particular aspects ofthe process, machine, manufacture, composition of matter, means,methods, and actions described above. Processes, machines, manufacture,compositions of matter, means, methods, or actions, presently existingor later to be developed, that perform substantially the same functionor achieve substantially the same result as the corresponding aspectsdescribed herein can be utilized. Accordingly, the appended claimsinclude within their scope such processes, machines, manufacture,compositions of matter, means, methods, or actions.
